#CMT# # / CMT# The device (10) has an oblong
printed circuit board including an insulating layer (12) and a conductive layer (11) connected to ground potential. The
printed circuit board has another conductive layer (13) formed of separated conductor sectors (14-17) that are connected in parallel to a
control equipment (25) and an optical luminous display (26) i.e.
LED display, via
signal output cables (20, 21), respectively. The
printed circuit board has contact bridges that connect the conductor sectors to the corresponding
signal output cables. #CMT# : # / CMT# An independent claim is also included for a gas insulated electric substation comprising a capacitive device for measuring
voltage of a

voltage of a
high voltage element e.g.
high voltage electrode such as high
voltage conductor, in an inner surface of a
metal case of a grounding switch of a gas insulated electric substation (claimed) i.e.
three phase sulfur hexafluoride insulated electric substation. #CMT#
ADVANTAGE : # / CMT# The device measures the voltage of the high voltage element in a simple and reliable manner. The device can be fabricated in an inexpensive manner. The device has reduced encumbrance and is small in size so as to permit the device to be installed in the substation in an easy manner. The device is configured such that the circuit board is changed to easily adjust the characteristics and
transmission rate of the device to obtain voltage and current of the high voltage element for different operating conditions of applications. The printed circuit board is oblong so as to create redundancy of information in an easy manner and to reduce the
distortion of a measurement
signal for specific utilization in the substation. The configuration of the device permits supply of power to the display without requiring an exterior
energy source. The device can be occupied in less space. #CMT#DESCRIPTION OF DRAWINGS : # / CMT# The drawing shows a perspective view of a capacitive voltage measuring device and a high voltage element. 10 : Capacitive voltage
